How Roth IRA Compares to a Taxable Account
A Roth IRA uses after‑tax dollars, meaning you pay taxes on contributions now but never on growth or withdrawals. A taxable account also uses after‑tax dollars, but you pay taxes on interest, dividends, and capital gains each year, reducing your net return. Over decades, the tax‑free compounding of a Roth IRA can result in significantly higher retirement savings — often hundreds of thousands of dollars more.
